Sony Ericsson today announced two new phones. The W580i builds on the Walkman series with a slider form-factor. The phone features EDGE, a 2 Megapixel camera, A2DP Bluetooth, and the latest Walkman 2.0 music player. Sony Ericsson is bundling the phone with a 512 MB Memory Stick.

The W580i is expected to ship in the United States next quarter, but no carriers were confirmed.
